Abstract

The clutch disc for a motor vehicle friction clutch comprises a friction lining carrier mounted rotatably on a hub, a torsional vibration spring means and a torsional vibration friction damper. The friction damper is arranged between side discs of the friction lining carrier and includes a spring of annular disc form and at least one friction ring seated in the support path. The installation height of the axially acting spring is variable after the assembly of the clutch disc, by an adjusting device. The adjusting device can be two adjusting elements rotatable in relation to one another, which vary the installation height of the spring by steps or steplessly. The adjusting device can also comprise permanently deformable adjusting elements or adjusting elements seated with press fit on the hub.
